Which of the following type of tissue is being described by the given statements ?
(i) They are named because of their special function of linking and supporting other tissues/organs of the body.
(ii) They include cartilage, bone, adipose and blood.
(iii) They provide strength, elasticity and flexibility to the tissue.
(iv) They also secrete modified polysaccharides, which accumulate between cells and fibres and act as matrix.

Which of the following statement is/are correct regarding digestive system of cockroach ?
(i) Mouth opens into a short tubular pharynx, leading to a narrow tubular passage called oesophagus.
(ii) Gizzard helps in grinding the food particles.
(iii) A ring of 6-8 blind tubules called hepatic or gastric caecae is present at the junction of foregut and midgut, which secrete digestive juice.
(iv) At the junction of midgut and hindgut is present another ring of 100-150 yellow coloured thin filamentous malphigian tubules which help in removal of excretory products from haemolymph.

1)
Only (i)
2)
Both (ii) and (iii)
3)
Both (i) and (iv)
4)
All of these

Solution:
Digestive system of cockroach is divided into - foregut, midgut and hindgut. The mouth opens into a short tubular pharynx which further opens into a narrow tubular structure called oesophagus. The oesophagus opens into a sac-like structure called crop where food is stored. The crop is followed by gizzard and proventriculus. The gizzard helps in grinding the food particles. The entire foregut is lined by cuticle. At the junction of foregut and midgut, a ring of 6 - 8 blind tubules are present. These are called gastric or hepatic cecae which secrete digestive juice. The hindgut is broader than the midgut. The hindgut is differentiated into ileum, colon and rectum. The rectum opens through anus. Malpighian tubulesMare the excretory organs which absorb nitrogenous wastes and convert them into uric acid. Uric acid is excreted out through the hindgut

Assertion : Intercalated discs are important regions of cardiac muscle cells.
Reason : Intercalated discs function as boosters for muscle contraction waves

1)
If both Assertion and Reason are true and the Reason is the correct explanation of the Assertion.
2)
If both Assertion and Reason are true but the Reason is not the correct explanation of the Assertion.

3) A – V; B – IV; C – III; D – II; E – I
4) A – III; B – IV; C – V; D – I; E – II

Solution:
Cuboidal epithelium is a single layer of cube shaped cells with a centrally located nucleus. Ciliated epithelium is a type of bodily tissues that is lined with "ciliated" cells, which are basically cells that have small, hair-like protrusions known as "cilia" that can either help the cells move along the tissue or can help debris and waste move along the surface of the cells. Columnar epithelial cells occur in one or more layers. The cells are elongated and column-shaped. The nuclei are elongated and are usually located near the base of the cells. Squamous cells have the appearance of thin, flat plates. The shape of the nucleus usually corresponds to the cell form and help to identify the type of epithelium. Keratinized squamous epithelium consists of multiple layers of squamous cells. The apical layer of cells are dead and filled with the protein keratin.

	Column-I (Types of connective)		Column-II (Examples)
a	Loose connective tissue	1	. Tendons and ligaments
b	Dense regular tissue	2	Skin
c	Dense irregular tissue	3	Cartilage, bones, blood
d	Specialized connective tissue	4	Fibroblasts, macrophages and mast cells

1) A – I; B – IV; C – II; D – III
2) A – I; B – IV; C – III; D – II
3) A – IV; B – I; C – II; D – III
4) A – IV; B – II; C – I; D – III

Solution:
Loose connective tissue (which includes areolar tissue, reticular tissue, and adipose tissue) holds organs in place and attaches epithelial tissue to other underlying tissues. It also surrounds the blood vessels and nerves. Cells called fibroblasts are widely dispersed in this tissue. Dense regular tissue includes tendons and ligaments. Tendon connects skeletal muscle with a bone. Ligaments attach one bone to another. Dense irregular tissue includes skin. Specialized connective tissue includes cartilage, bones and blood. Cartilage is a rubbery tissue made by cells called chondroblasts. It does not have any blood vessels within it so healing is not easy if it is damaged and may not occur at all if the damage is extensive enough. Bone is a rigid organ that constitutes part of the vertebral skeleton. It support and protect the various organs of the body, produce red and white blood cells, store minerals and also enable mobility. Blood delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away.

Gause’s ‘competitive exclusion principle’ states that

1)
humans are the most widespread agents of disturbance.
2)
in a competition for similar resource both the participants are benefitted.
3)
in a competition, both the participants are excluded.
4)
two closely related species competing for the same resources cannot co-exist indefinitely and competitively inferior one will be eliminated eventually.

Identify the correct statement.

1)
The smaller animals have larger surface area relative to their volume.
2)
Smaller animals are rarely found in polar region.
3)
Bear cannot migrate hence hibernate during winter.
4)
All of the above

Solution:
Small animals have a large surface area relative to their volume. They tend to lose body heat very fast when it is cold outside; then they have to spend much energy to generate body heat through metabolism. This is the main reason why very small animals are rarely found in polar regions. Hibernation is a time when animals ‘sleep’ through cold weather. The familiar case of bears going into hibernation during winter is an example of escape in time.
